Is it legal to record a conversation in New Zealand?

Back to Insights

People reach for a recorder when they want proof: a difficult employment process, a business dispute, a relationship breakdown, a tenancy problem, a complaint where you suspect the other side will later deny what was said. A recording feels like protection.

Sometimes it is. Just as often, it creates a new problem, one that lands on you rather than the person you were worried about. This article explains where the line actually sits, and how to avoid the mistakes that turn a recording from an asset into a liability.

What the law actually says

New Zealand is often described as a "single-party consent" country. In plain terms, if you are part of a conversation, recording it is generally not a criminal offence under the Crimes Act, even if no one else in the room knows.

The relevant provision is section 216B of the Crimes Act 1961. It makes secret recording an offence in one specific situation: when you record a private conversation that you are not a party to, using a recording device. Doing that can carry up to two years' imprisonment. Section 216C then makes it a separate offence to disclose a private communication that was unlawfully intercepted.

The dividing line is simple to state:

• A conversation you are in: generally lawful to record, with or without the other person's knowledge.
• A conversation between other people that you are not part of: recording it covertly can be a crime, and sharing it compounds the offence.

That is the legal floor. Now the harder part.

Legal does not mean safe

Being legally entitled to make a recording does not guarantee it will help you. Audio captures far more than a written note: tone of voice, pauses, off-hand remarks, other people's names, personal details no one expected to be kept. That very richness can later be turned against the person who made it.

A decision-maker rarely asks simply whether it proves the truth. More often the question is whether it was fair and reasonable to make the recording, and how it was handled afterwards.

Someone who records out of genuine fear for their safety looks very different from a person who routinely tapes every interaction just in case. This is especially live in employment. Even where a recording is lawful, employers and employees owe each other a duty of good faith, and the Employment Relations Authority has treated covert recording as capable of breaching that duty, regardless of the Crimes Act position. Lawful and acceptable are not the same thing.

The mistakes that turn a recording against you

Recording everything

Sweeping up unrelated private information looks excessive, and invites questions about why you collected so much and what you did with it.

Sharing it around

Having a reason to make a recording does not give you a reason to post it online, forward it to friends, or use it to shame someone. Disclosing an unlawfully obtained recording can itself be an offence under section 216C; even a lawful one damages your credibility when misused.

Using it as leverage

"I have you on tape, so do what I say" almost always backfires, shifting the focus off the original issue and onto your conduct.

Treating it as the whole case

A single recording shows only one conversation. It omits the context, the body language, the prior messages, the wider pattern. It is one piece of evidence, not the answer.

Editing or trimming it

If you might rely on a recording, never alter it. Keep the original file, and preserve the date, time, device details, and any related messages. A recording that has been cut, renamed, compressed, or transferred invites questions about whether it is complete and reliable, and those questions can sink it.

Recording workplace meetings

Employers: if you want to record a meeting, say so first. Something like: "We would like to record this discussion so there is an accurate record, and we can share a copy afterwards." Clear, fair, and it removes the good-faith problem before it starts.

Employees: if you feel you must record secretly because you do not trust the process, pause. You usually have better options:

• Ask to record the meeting openly.
• Bring a support person to take notes.
• Make your own contemporaneous notes.
• Request formal minutes.
• Send a follow-up email confirming your understanding.
• Ask for the key points to be put in writing.

A matter serious enough to trigger a hidden recorder is serious enough to get advice first.

Will a secret recording be accepted as evidence?

Possibly, but never assume it.

Even a lawfully made recording can be challenged on fairness, relevance, reliability, and privacy. In criminal proceedings, section 30 of the Evidence Act 2006 requires a judge to weigh the value of improperly obtained evidence against the impropriety in how it was obtained, and the evidence may be excluded. In employment and civil matters, a decision-maker looks at fairness, relevance, reliability, privacy, and the circumstances of the recording.

New Zealand tribunals have admitted improperly obtained recordings where the value outweighed the concerns, and have refused others. You cannot predict the outcome from the recording alone. That uncertainty is precisely why a recording is a double-edged sword: it may support your account, or it may hand the other side a fresh argument about your behaviour.

When recording without consent carries more weight

There are situations where it carries more weight and less risk:

• You are concerned for your personal safety.
• Threats or abusive behaviour are occurring.
• You are preserving evidence of serious misconduct.
• There is no practical alternative way to make an accurate record.
• Asking for consent would make the situation worse.
• The other person is likely to flatly deny what was said.

Even then: keep it limited to what is necessary, store it securely, do not share it, do not edit it, do not repurpose it. And get advice.

Cleaner alternatives before you press record

A follow-up email is often the strongest option:

It creates a dated written record and gives the other person a chance to correct it, without recording anyone.

• Contemporaneous notes made at the time or shortly after, with date, time, who was present, what was discussed, exact words recalled, what was agreed, carry real weight.
• Asking openly ("Would you mind if I record this so my notes are accurate?") drops the risk dramatically if the answer is yes.
• A support person at a sensitive meeting, or requesting minutes you can correct in writing, both achieve the goal without covert recording.

How an investigator reads a recording

A good investigator never takes a recording at face value. It gets tested:

• What does it actually prove?
• Is the full conversation present, or just a slice?
• What happened before and after?
• Who made it, and why?
• Was anyone told?
• Has the original been preserved, or has it been edited, renamed, compressed, or shared?
• Does it line up with emails, texts, documents, CCTV, or witnesses?
• Does it strengthen the position, or open a new line of risk?

The job is not to collect information. It is to assess it properly, for reliability, relevance, lawfulness, and usefulness. A recording that looks like a knockout blow can turn out to be the weakest part of a file, and a single text message can turn out to be the strongest.

If you already have a recording

Do not panic, but be careful about what you do next.

Do not post it online. Do not forward it. Do not edit it. Do not threaten anyone with it. Do not assume it proves everything.

Keep the original safe. Note when and why you made it, who was present, and what it covers. Then get advice before you use it.
